jquery - 如何在 jQuery 中对数组使用 $.each 方法？

Question

function calcTotalScore(){
    var arr = ["A","B","C","D","E","F"];
    $.each(arr, function(n,val){
        calcTotal(val);
    });
}

calcTotal(value){
// sample code
}

我calcTotalScore()在速度模板语言（VTL）中使用上述函数，但它说：

Encountered "," Was expecting one of:
   <EOF> 
    "(" ...
   <RPAREN> ...
   <ESCAPE_DIRECTIVE> ...
   <SET_DIRECTIVE> ...
   "##" ...
   "\\\\" ...
   "\\" ...
   <TEXT> ...
   "*#" ...
   "*#" ...
   <STRING_LITERAL> ...
   <IF_DIRECTIVE> ...
   <STOP_DIRECTIVE> ...
   <INTEGER_LITERAL> ...
   <FLOATING_POINT_LITERAL> ...
   <WORD> ...
   <BRACKETED_WORD> ...
   <IDENTIFIER> ...
   <DOT> ...
   "{" ...
   "}" ...

我究竟做错了什么？

Answer 1

VTL 将 jQuery 解释$为变量的开始。然后它会抱怨，因为变量名不能以点开头。

你有两个选择：

1. 用反斜杠转义美元，例如。\$
2. 使用jQuery代替$

您只是在 calcTotal 前面缺少一个“函数”；）

function calcTotalScore(){
    var arr = Array("A","B","C","D","E","F");
    $.each(arr, function(n,val){
        calcTotal(val);
    });
}

function calcTotal(value){
// sample code
    alert(value);
}

calcTotalScore();
